One number is 2 less than a second number. Twice the second number is 17 less than 5 times the first

gulaghasi [49]

X=y-2
2y=5x-17
Substituting for x into the second equation, we find
2y=5(y-2)-17
2y=5y-10-17
-3y=-27
y=9
So x=7
Thus, the two numbers are 7 and 9.

Find x in each triangle. PLZ HELP!!!

jonny [76]

Answer:

x=3.4

Step-by-step explanation:

Use the Pythagorean theorem:

$a^2+b^2=c^2$

a and b are the legs and c is the hypotenuse (x)*

Insert the values:

$3^2+1.6^2=x^2$

Simplify exponents

$9+2.56=x^2$

Simplify addition:

$11.56=x^2$

Find the square root:

$\sqrt{11.56}=\sqrt{x^2}$

$3.4=x\\x=3.4$

Finito.

*The hypotenuse is the side opposite the 90° angle and the longest side of a triangle, always.
